SA'SI-I ADJUSTER AND "ras'rnivnn.

Application filed March 1231926. "Serial No. 94,175.

This invention relates to builders hardware-and hasparticular referenc-eto a storm sash adjuster and fastener for application to storm sash or screens and for use with any tophung hangers.

The principal object of the invention isto Jrovide adevice of this character which inay be used either with storm sash -or screens.

Another object is to provide such a device which cannot rattle when it is holding the storm sash open.

Further objects and advantages of the invention will appear in the further description thereof.

Referring now to the accompanying drawing, forming part of this application, and wherein like reference characters indicate like parts:

Figure 1 is a broken, side elevation of the device as applied to a window stop and storm sash, and illustrated as holding the latter open;

Figure 2 is an end view of the same;

Figure 3 is a side elevation of the device as applied to a window stop and screen;

Figure 4 is a combined perspective view of the cooperative parts when the device is used for holding a screen in place on the window; and

Figure 5 is a view of the free end of the operating rod.

In the drawing, 1 represents the stop which is fixed to the inner face of the win- .dow frame and against the outer face of which stop the storm sash or screen abuts as the case may be. To the inner face of the stop 1 is fixed the angularly shaped bracket 2, the outwardly projecting flange 3 of which is provided with the T-shaped slot 4 within which the operating rod 5 is designed to reciprocate as is common. One end of the rod 5 is bent at right angles as at 6 forming an inwardly projecting portion or handle for operating the device conveniently,

and the other end of the rod is pivotally connected to the bracket 7 secured to either the screen or storm sash as desired.

All of the foregoing is common in the ordinary storm sash fasteners and the particularly novel features of the invention herein described is believed to bein the cam like lock, pivotally secured, as at 9, to the flange 3, and having its free end bent at right angles as at 10 forming a convenient means for manually moving the same about its axis.

This cam is for-engagement with the:rod.5 in either ofzthe slots 11 iformedin the-upper edge of said rod, one-immediately adjacent the ,handle 6 and atleast one=other it'iLz-SOlTlG desired point intermediate its-ends, or with in the-slot 12 in the bracket l7 :In-Figures 1 and..2 the cam .is shown Jill engagement within the slot 11 adjacent the .handlexG, whileinFigure 3 itis shownengaged .within the slot 12. Directly opposite the slots 11 and in the other edge ofthe'rod 5 are slots 13 which are designed to straddle the material of which the flange 3 isformed and in the T-slot 4, as is common. The slots 11 are twice the width of the slots 13 and so positioned that when either of the slots 13 engages the flange 3,- the opposite slot 11 will register with the cam 8 when it is moved about its axis, the cam face or edge binding the rod 5 in the slot 4 so that the same cannot move or rattle. When the storm window I is pulled in so that it abuts against the outer face of the stop 1, the cam 8 will engage the slot 12 in the bracket 7 securely holding the same and the windowin closed position, and the rod 5 will swing downwardly to a vertical position longitudinally of the stop 1 and the hole 14 slip over a pin fixed therein, as is common.

WVhen this device is used, obviously the vantage of this type of fastener for screens is obvious, as the same may be applied to the window from the inside thereof and made secure by the cam binding the bracket 7 in the slot 12.

The rod 5 may be freed from the slot 4 by reciprocating the same therein until the opposed slots 11 and 13 are in longitudinal alignment with the flange 3 when the rod will slip laterally from the slot 4, as is common in the ordinary fastener.

From the foregoing it is evident that I have devised an exceedingly simple and practical storm sash fastener and one that will positively prevent the rod 5 from being disengaged from its bracket when the lit storm window is open and which will not rattle in any position.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. In combination, an angular bracket one flange of which is adapted to be secured to a window stop and the other flange having a T-shaped slot therein, an angular bracket one flange of which is adapted to be secured to a storm sash for the window and having a notch in the other flange, an operating rod one end of which is pivotally connected to the sash bracket and adapted to reciprocate in the T-shaped slot, and means for securely holding the rod or bracket from dislodgment from the T-shaped slot.

2. The combination with a window including a stop, and a storm sash or screen therefor, of an angular bracket having a T-shaped slot therein secured to the stop, an angular brackethavinga notch therein secured to the storm sash or screen, and means pivotally fixed to one of the brackets for cooperative engagement with the notch in the other bracket, transverse the slot. 7

3. A storm sash or screen fastener adapted to be secured to the stop of a window frame comprising an angularly shaped bracket having a T-shaped slot therein, and 11V a cam pivotally fixed within the angle of said bracket for cooperative adjustment transverse the slot.

In testimony whereof I hereunto afiix my signature.
